Step 1 : Introduction to the question "2. Which Revisionist Western starred Richard Harris in the title role, as an English aristocrat who was captured by the Sioux? The movie spawned two sequels."
...1. Ride with the Devil 2. Death Rides a Horse 3. Navajo Joe 4. A Man Called Horse In "A Man Called Horse" (1970) Richard Harris played English aristocrat John Morgan, who was captured by the Sioux while on a hunting expedition in the Dakotas. He was spared because of his blond hair. At first he was used as a slave but he soon accepted the Sioux ways and proved himself according to their customs. From slave he rose eventually to lead the tribe. The sequels were "The Return of a Man Called Horse" (1976) and "Triumphs of a Man Called Horse" (1983). The movie was revisionist because it painted the Sioux as neither noble savages nor cliched villains, but looked more objectively at both white culture and Native American culture. The film was noted particularly for its graphic portrayal of the Sun Vow ceremony. Some Native American activists have complained that even though it attempted to portray Native Americans more favorably, it still was from a white man's perspective. Considering the time that it came out, the movie made great strides in being more fair and balanced, despite this criticism.
